Captain Max Pacioretty, who had a scary moment of his own back in 2011 when he was hit by Boston Bruins defenceman Zdeno Chara, said it was worrying to see "that many trainers and doctors on the ice."

"Nobody knew exactly what happened," Pacioretty said after the game.

"That was the scariest part for me. It looked like a nothing play. It was impossible to concentrate after that."
